BUTTONOR STUD.

SPECIFICATION forming part of Letters Patent No. 424,153, dated March 25, 1890.

Application led May l0, 1889. Serial No. 310,293. (No model.)

To all whom t may concern.- 5

Be it known that we, AMOS WHITNEY, of

Hartford, in the county of Hartford and State of Connecticut, and HIRAM HOWARD, of Providence, in the county of Providence and State of Rhode Island, have invented a certain new and useful Improvement in Buttons or Studs, of which the following is a specification.

Our improvement relates particularly to ro that kind of button or stud which has the head rigidly secured to the shank or post.

The object of the improvement is to produce a button which may be inserted in a button-hole and removed therefrom with greater facility than that which is attained by the ordinary construction.

y The improvement also involves the construction of the head of a button or stud, so

as to conduce to' the safety of a stone or zo stones iitted to the head..-

The improvement consists in a button having a head made convex at the rear or back, and having at the front no projection beyond that of the edge portion.

2 5 The improvement also consists in a button having a head made convex 'at the rear or back and concave at the front adjacent to the edge portion.

The improvement also consists in a button 3o having a head made convex at the rear or` back and concave at the front, and provided at the concave side with a seat for a stone or stones.

In the accompanying drawings, Figure l is 3 5 a side view of a button or stud embodying our improvement.

tudinal section of the same. Fig. 3 is a front view. Fig.- Il is a transverse sect-ion taken through the shank or post in rear of the head.

4o Fig. 5 is a front view of a button or stud constructed according to our improvement and having a stone set in the head. All these views have been made upon a large scale, so as to illustrate the novel features most clearly.

Similar letters of reference designate correspondin g parts in all the iigures.

A designates the back-plate of the button or stud. B designates the shank or post, and

Fig. 2 is a central longif C designates the head. This button or stud 5o -may be made of any desirable material or materials, and the parts may be united in any manner. These details are immaterial so far as our improvement is concerned, as the improvement resides in the form or shape Vof the head.

It will be seen that no portion of the head projects farther forward than the edge portion, and that the back of the head is con- Vex or has a gradual slope or curve from the 6o periphery toward the shank. This is a very advantageous construction in that it makes the edge portion of the head Wedgeshaped, thereby facilitating its entrance into a button-hole. The head is shown as of concavoconvex form, the concave side being at the front and having its deepest portion in the axial line of the post. This concave or cupshaped front is advantageous in that it enables the head of the button to be easily held 7o from the front in the act of inserting it into abutton-hole. It also affords a place into which the edge portion of a button-hole may be depressed during the passage of the head of a button through the button-hole.

Another and by no means unimportant advantage resulting from making the front of the head with a salient edge or concave arises from the safety which it affords stones inserted in the head. The concave construc- 8o tion causes the' edge portion of the front of the head to project so far forwardly as to prevent most things fromcoming into contact with stones setin the head.

Vhat We claim as our invention, and desire 8 5 to secure by Letters Patent, is

l. A collar-button provided with the cus tomary shank or post and back-plate and aY face plate or disk formed concave or cupshaped, the deepest portion of the concavity 9:) being in the axial line of the post and extending to the periphery of thev disk or plate, said periphery or edge being made thinner than the body of the plate, substantially as specified.

2. A collar-button provided with the customary shank or post and back-plate and a face plate or disk formed concave or cupshaped, the deepest portion of the eoneavity back sloped or curved from the edge rearbeing in the axial line of the post and e. ward toward the shank or post, substantially tending to the periphery of the disk, the said as specified.
